Doc Text:	.OVAL checks consider GPFS as remote Previously, the OpenSCAP scanner did not identify mounted General Parallel File Systems (GPFS) as remote file systems (FS). As a consequence, OpenSCAP scanned GPFS even for OVAL checks that applied only to local systems. This sometimes caused the scanner to run out of resources and fail to complete the scan. With this update, GPFS has been included in the list of remote FS. As a result, OVAL checks correctly consider GPFS as a remote FS, and the scans are faster.	Story Points:	---

Description Renaud Métrich 2020-05-27 09:14:16 UTC

Description of problem:

This is a continuation of BZ #1840578 and BZ #1694962.

As of today, GPFS file systems are not considered as remote file systems, which cause some oscap rules to recurse in such file systems, causing various issues:
- slowness of the scan
- high memory usage

There should be a convenient way to exclude such file systems automatically or administratively through some configuration file.
Customers cannot rely on the workaround described in KCS https://access.redhat.com/solutions/4193501.

For example, if the proposed solution in BZ #1840578 is implemented, this could be easily implemented through specifying "InaccessibleDirectories" systemd property.

Comment 1 Jan Černý 2020-06-30 13:59:35 UTC

We have discussed this internally.

We would like to change the OpenSCAP so that it recognizes GPFS as a remote system. GPFS volumes would be skipped in all rules where the OVAL object definition uses `recurse_file_system` attribute set to `local`. In similar way, we already skip NFS, SMB and other network file systems in these rules.  This solution means that to exclude the remote file systems and GPFS it requires changes on content side: all the rules must use this `recurse_file_system` attribute.

However, we don't want to provide a command line option that excludes specific paths because that would mean the option would override the instructions in SCAP content. We think that it would mean the scanner would behave differently from the specification.
